Specific embodiment
The pressure of fluid control devices (for example, valve, pressure regulator etc.) etc keeps equipment to generally include at least
Two body parts, at least two body part tighten together to create and keep the close of the pressure relative to atmospheric pressure
Seal cavity.Many known pressure keep equipment to be fixed to one another body part using threaded stud and nut.Known to these
Design needs a large amount of process that threaded stud is inserted into a body part in body part.For example, threaded stud is logical
It often include stop screw thread, the stop screw thread is for controlling the depth that stud can advance in body part, so that threaded stud
Specific length be arranged in body part, and specific length extends outwardly from body part.This cause stud have want
It is coiled into the specific direction into body part.In some cases, stud may be installed unintentionally backward.In this way, must move
The stud is reinstalled except stud and to be correctly oriented.In addition, threaded stud must often lubricate before insertion, to increase
The convenience of installation and removal.In some cases, threaded stud must also be easy for the double nut of installation, so that stop screw thread
It can correctly engage.These processes have slowed down the speed that stud is installed in body part, and which results in times and cost.This
Outside, in some cases, such as valve body, there must be minimum wall thickness (MINI W.) to meet industry mark around threaded stud in valve body
Quasi- (for example, American Society of Mechanical Engineers (ASME), American National Standards Association (ANSI) etc.), which increase sizable valves
Height, the weight of body, and therefore increase cost.
Example pressure disclosed herein keeps equipment to replace above-mentioned known threaded stud using welding screw.By making
Threaded stud is replaced to reduce manufacture and built-up time come the body part of fixation pressure holding equipment with welding screw.In addition,
The use to stop screw thread is no longer needed, it is thus eliminated that a possibility that being inserted back into stud.Moreover, welding screw is in insertion
Before need not lubricate.In addition, welding screw is obviously shorter than threaded stud, and pressure guarantor is extended to unlike threaded stud
In the ontology of holding equipment (if any).Therefore, meet the extra height and again that minimum wall thickness (MINI W.) requirement does not increase body part
Amount.
Before the details for being described in conjunction with the accompanying example welding screw disclosed herein, mentioned below with reference to Fig. 1,2A and 2B
For the brief description of known control valve for fluids 100.As shown in Figure 1, control valve for fluids 100 includes valve body 102,104 and of bonnet
Actuator 106.Known threaded stud 108 (two therein referring to Fig. 1) is used to bonnet 104 being fixed to valve body 102.
As shown in Figure 2 A, valve body 102 is limited to first entrance/outlet 202 to the fluid between second entrance/outlet 204
Flow path 200.Control member 206 (for example, plug) is arranged in the cavity 208 of valve body 102 and is coupled to valve rod
210.Valve rod 210 is coupled to actuator 106 (Fig. 1), and the mobile valve rod 210 of actuator 106 is to change control member 206 in cavity
Position in 208, and stream between first entrance/outlet 202 and second entrance/outlet 204 is flowed through to modify fluid
The rate of body flow path 200.Specifically, control member 206 can be mobile towards or away from seat ring 212.In order to close valve
100, control member 206 is moved to be engaged with seat ring 212, to prevent fluid flow through valve body 102.In order to open valve 100, control
Component 206 is mobile far from seat ring 212, this allows fluid to flow through between first entrance/outlet 202 and second entrance/outlet 204
Fluid flow path 200.As shown in Figure 2 A, cavity 208 is limited by valve body 102 and bonnet 104, and valve body 102 and bonnet 104 are logical
It crosses threaded stud 108 to be coupled, cavity 208 and ambient enviroment sealing be separated, and pressure (and fluid) is maintained at valve
In body 102.The control valve for fluids 100 of Fig. 2A further includes packing stud (packing stud) 213, according to present disclosure and
The one or more principles being further disclosed in detail herein, the packing stud can be replaced by example welding screw.
Fig. 2 B shows one enlarged view in the threaded stud 108 in Fig. 2A.As shown in Figure 2 B, threaded stud
Bonnet 104 is fixed to valve body 102 by 108.Threaded stud 108 is partially disposed at the spiral shell in the surface 216 for being formed in valve body 102
In pit 214.Threaded stud 108 extends outwardly from threaded hole 214 and passes through the channel 218 in the flange 220 of bonnet 104
(for example, reach through hole).Nut 222 is coupled to threaded stud 108 so that bonnet 104 is fastened to valve body 102.
Threaded hole 214 is formed by drilling in valve body 10 with tapping.As shown in Figure 2 B, threaded hole 214 is relatively deep
To ensure being sufficiently threadedly engaged between threaded stud 108 and threaded hole 214.In addition, threaded hole 214 is by pilot hole/guide hole
A part of formation is prolonged than the threaded portion of threaded hole 214 to be projected farther.Therefore, valve body 102 need have bigger thickness with
Ensure that there are the materials of sufficient amount around threaded hole 214 to meet industrial standard (for example, ASME, ANSI etc.).Specifically, exist
In Fig. 2 B, the wall 224 of threaded stud 108 and valve body 102 is spaced the first material thickness 226.First material thickness 226 indicates screw thread
It must be provided between stud 108 and wall 224 to meet the minimum thickness of industrial standard.The industrial standard must be satisfied, because
The hole of middle appearance or gap during molten metal solidifies are possibly comprised in for casting.Specifically, when drilling in founding materials
When with tapping, it is possible to pierce the region with gap or pore area.These gaps may cause so that pressure keeps equipment
The seal cavity of middle leakage.Therefore, additional height and weight are increased in valve body in accordance with Industry standards call, which increase
Manufacture the cost of control valve for fluids 100.
In some cases, threaded stud 108 includes stop screw thread, and the stop screw thread is for preventing threaded stud to be screwed to spiral shell
The bottom of pit 214.However, threaded stud 108 can be screwed onto screw thread if threaded stud 108 is unintentionally installed backward
Hole 214 is too deep or inadequate, thus the length of the inside and outside screw bolt 108 for leaving mistake in threaded hole 214.This
In the case of, threaded stud 108 must be removed and be reinstalled with being correctly oriented.When manufacturing control valve for fluids 100, the mistake
Journey needs additional time and cost.
In some cases, it can be possible to need to dismantle bonnet 104 and valve body 102 (for example, to replace in control valve for fluids 100
Washer).In this case, nut 222 will be backed out from threaded stud 108.However, usually nut be corroded and/or with
Other way is sticked on threaded stud 108.In this way, threaded stud 108 is backed out from valve body when nut 222 rotates.Some
In the case of, after removing nut 222 and threaded stud 108, it is necessary to remove nut from threaded stud 108 using individual technique
222 and suitably reinstall nut 222.These tasks also add manufacture and the built-up time of control valve for fluids 100.?
In other situations, the overhang of valve can be arranged directly on the top of nut and threaded stud 108, this can prevent screw thread spiral shell
Column 108 is removed.In this case it is necessary to which largely machining is to dismantle these components.
Fig. 3 shows the example fluid control valve using example welding screw 302 of the introduction according to present disclosure
300.Example welding screw 302 can be used for coupling two structures (for example, ontology) of control valve for fluids 300.Institute
In example, example welding screw 302 is used to for example bonnet 304 being fixed to example valve body 306 (for example, fluid control is originally
Body), pressure is kept to form seal cavity 308.The stream of Fig. 1-2 B is replaced it is, for example, possible to use example welding screw 302
Any of threaded stud 108 of body control valve 100.Shown in example only show by example bonnet 304 be fixed to example
One example welding screw 302 of valve body 306.However, in other examples, there may be the welding screws of multiple annular spaces
302 to be fixed to valve body 306 for bonnet 304.
In the example depicted in fig. 3, valve body 306 includes surface 312, and bonnet 304 will be coupled to the surface 312.Welding
Stud 302 extends outwardly from surface 312 and is passed through the channel 318 in bonnet 304 (also referred to as reach through hole or through-hole).?
Shown in example, channel 318 forms the flange 326 between lower flange surface 328 and upper flange surface 330 of bonnet 304
In.However, in other examples, channel 318 can be formed in another part of bonnet 304.
In the example shown, the first end 332 of welding screw 302 is welded to the surface 312 of valve body 306.Show some
In example, example welding screw 302 is welded to the surface 312 of valve body 306 using welding screw rifle.However, in other examples,
Welding screw 302 can be used another welding equipment and be welded to surface 312.In this example, valve body 306 consists of metal.
However, in other examples, valve body 306 can be by being suitable for that any other material of pressure is kept to constitute.
The second end 334 opposite with first end 332 of welding screw 302 extend outwardly from the channel of bonnet 304 318 and
Receive screw nut 336.For example, screw nut 336 may be screwed on welding screw 108 until it contacts the convex of bonnet 304
Edge surface 330.Nut 336 can be tightened further further to fasten bonnet 304 and valve body 306.
In the example shown, welding screw 302 includes first part 338 and second part 340: first part 338 is not
Including screw thread and there is smooth cylindrical surface, and second part 340 includes screw thread 342.However, in other examples
In, the first part 338 of welding screw 302 can be threaded.In other words, entire welding screw 302 can be band spiral shell
Line.
In the example shown, bonnet 304 includes extension 344, and extension 344 extends to the table for being formed in valve body 306
In recess 346 in face 312.As shown in figure 3, extension 344 and recess 346 formed for sealing element 350 (for example, O-ring,
Washer etc.) sealing gland 348, help to make seal cavity 308 to seal.In the example shown, extension 344 and recess
346 are sized so that when bonnet 304 is coupled to valve body 306, in the surface of valve body 306 312 and bonnet 304
The gap 352 with clearance height 354 is formed between lower flange surface 328.In other words, when bonnet 304 is assembled into valve body 306
When, surface 312 and lower flange surface 328 are separated from each other.In this example, gap 352 surrounds welding screw 302.However,
In other examples, the size of extension 344 and recess 346 can be designed so that clearance height 354 can be smaller or larger.?
In some examples, the surface 312 of valve body 306 and the lower flange surface 328 of bonnet 304 can be contacted.
As shown in figure 3, the second thickness 356 of material be limited to valve body 306 surface 312 and valve body 306 wall 358 it
Between.According to application, second thickness 356 must satisfy industrial requirements identical with the threaded stud 108 of Fig. 2A and 2B.However, because
It is not extended in valve body 306 for welding screw 302, so valve body 306 can may be significantly smaller (for example, narrower, shorter etc.), together
When still meet industrial standard (for example, ASME, ANSI etc.).This cause the height reduced during manufacturing process, weight and at
This.Therefore, it may seem wider although valve body 306 is in Fig. 3, valve body 306 can narrow or shorten, to reduce for manufacturing
The quantity of material of valve body 306.
Moreover, example welding screw different from the known thread stud that may be backed out unintentionally when attempting and removing nut
302 are fixedly coupled to valve body 306, and therefore when backing out screw nut 336, the example welding screw 302 not can rotate.
Therefore, cause less time and cost when executing this task.In addition, because welding screw 302 is unlike the spiral shell in Fig. 2 B
Line stud is screwed into hole like that, it is thus eliminated that the needs to stop screw thread and avoiding associated disadvantage (for example, must
Threaded stud must be reinstalled).
Fig. 4 is indicated for installation example welding screw 302 and the example that couples valve body 306 and bonnet 304
The flow chart of method 400.The exemplary method of sequence description Fig. 4 in conjunction with shown in Fig. 5 A-5D.
At frame 402, welding screw 302 is coupled to the surface 312 of valve body 306.In some instances, such as institute in Fig. 5 A
Show, welding screw 302 is welded to surface 312 by using welding screw rifle 502 and is coupled to surface by welding screw 302
312.In the example shown in Fig. 5 A, welding screw rifle 502 is arc stud welding machine.Welding screw rifle 502 includes chuck 504, weldering
It connects stud 302 and lasso 506 (for example, ceramic ring) is manually or automatically and is inserted into the chuck 504.Lasso 506 is assembled by electric current
The heat of generation prevents from aoxidizing, and keeps molten metal in welding region.Welding screw rifle 502 includes support bottom
(foot) 512 column 508,510.As shown in the amplification mark in Fig. 5 A, bottom 512 is carried out against the surface of valve body 306 312
It places, so that 506 contact surface 312 of the first end 332 of welding screw 302 and lasso.Trigger on welding screw rifle 502
